As shown in Fig. 1 (a), bottom fixed part 10 is made up of insertion section 12 and engaging part 13, and the following matrix side component 14 in insertion section 12 and engaging part 13 is formed at the end of the longitudinally of longitudinal bands 2.

Insertion section 12 is formed as the relatively thin plate shape shape of thickness, can be inserted in the groove portion of the main body 7a being formed at slide block 7.And, the lateral margin of insertion section 12 extends to towards the midway of engaging part 13 side along the longitudinally of longitudinal bands 2, but be formed as to the bending shape of the side without the side of element 4 of longitudinal bands 2 from this midway, when combining bottom fixed part 10 and bottom fixed part 11, this insertion section 12 can be avoided mutually to interfere with slide block receptacle 17 grade of bottom fixed part 11.

In addition, in this embodiment, insertion section 12 is formed with element 4a(hereinafter referred to as the first element in the side contrary with downside end of the longitudinally of longitudinal bands 2).The shape of this first element 4a also can be special shape, easily suitably to engage with the first element 4b of following longitudinal bands 3.

As shown in Figures 2 to 4, engaging part 13 is made up of matrix side component 14, lid side component 15 and elastomer 16 3 parts.

As shown in Figure 2, matrix side component 14 is such as formed by with lower part: the flat substrate 141 be integrally formed with insertion section 12, the thickness direction along longitudinal bands 2 of substrate 141 are circular outstanding incorporating section 142 and insertion section 143, and this insertion section 143 extends towards bottom fixed part 11 side after the thickness direction of longitudinal bands 2 protuberance from position near the end of bottom fixed part 11 side of substrate 141.As shown in Figure 2 (c), substrate 141, incorporating section 142 and insertion section 143 are integrally formed.

As shown in Fig. 2 (b) He Fig. 2 (c), the thickness of the Thickness Ratio insertion section 12 of substrate 141 is large, has required size, thus ensure that intensity.In addition, in this embodiment, in order to ensure the position etc. forming incorporating section 142, as shown in Figure 2 (a) shows, the Breadth Maximum of the longitudinally along longitudinal bands 2 of substrate 141 is larger than the width of the longitudinally along longitudinal bands 2 of insertion section 143.As shown in Figure 2 (a) shows, matrix side component 14 is the outstanding shape be made up of substrate 141 and insertion section 143, and following lid side component 15 also as Fig. 3 (a) is depicted as outstanding shape, thus avoids lid side component 15 and rotates under the state covering matrix side component 14.

Incorporating section 142 for formed together with the incorporating section 152 of following lid side component 15 receive elastomer 16 accommodation space S(Fig. 4 shown in.）。In this embodiment, as shown in Figure 2 (a) shows, the center P1 of incorporating section 142 is positioned at the position slightly in the inner part of the lateral margin without the side of element 4 than longitudinal bands 2, but is not defined in this.As long as such position: in the incorporating section 152 of assembling lid side component 15, when engaging part 13 is gripped in the mode that the size of its thickness direction reduces, lid side component 15 and matrix side component 14 can not rock vertically close to and away from direction on relative movement.In addition, the thickness forming the circular protuberance of incorporating section 142 has required size, thus ensure that intensity, and the outside dimension of incorporating section 142 also has required size, thus ensure that intensity.

In this embodiment, as shown in Figure 2 (a) shows, insertion section 143 is extended on the axis L1 extended along the width of longitudinal bands 2 by the center P1 of incorporating section 142, observe from side and be identical width, namely, upper lateral margin line and lower lip line parallel, with this axis L1 for datum line is configured to roughly symmetric shape.Further, as shown in Figure 2 (c), about insertion section 143, the position of protuberance and the position of end side all have required thickness, thus ensure that intensity.On the other hand, about insertion section 143 from the side, incorporating section 142 position that substrate 141 swells, when incorporating section 142 is combined with the incorporating section 152 of lid side component 15, in order to not hinder the combination of incorporating section 142 and incorporating section 152, as shown in Fig. 2 (a) to Fig. 2 (c), and otch is arcuation.

As shown in Figure 2 (a) shows, terminal edge point centered by a P2 of insertion section 143, expand into the arc-shaped of the semicircle being of a size of the positive round of diameter with the width of insertion section 143.That is, about the terminal part of this insertion section 143, the size (size of the width of insertion section 143) along the longitudinally of the longitudinal bands 2 by the some P2 of insertion section 143 be 2 times of the size of axis L1 along the some P2 passing through insertion section 143.Further, the end of insertion section 143 is not only given prominence to than the side of insertion section 12 in this embodiment, and gives prominence to than element 4,4a.Certainly, insertion section 143 terminal edge is not defined as above-mentioned arc-shaped, although do not illustrate, yet can be linearity and make end section be the quadrangle form with an angle of 90 degrees.

Further, matrix side component 14 stretches out from substrate 141 lower portion fixed part 11 side by making rib 144, and between rib 144 and insertion section 143, be formed with locking depressed part 145.This locking depressed part 145 can engage with the following locking teat 181 of the chest portion 18 of bottom fixed part 11.

As shown in Figure 1, the outer shape of lid side component 15 is larger than the outer shape of matrix side component 14, and lid side component 15 plays function as the upper cover covering matrix side component 14 entirety.And, as shown in Figure 3, lid side component 15 is formed by with lower part: for the heavy section 151 guaranteeing intensity, the incorporating section 152 of circular hole with the end of caving in along the thickness direction of the longitudinal bands 2 of substrate 141 in heavy section 151 and the insertion section 153 extended towards this bottom fixed part 11 side from bottom fixed part 11 side of heavy section 151.As shown in Figure 3 (c), the heavy section 151 comprising incorporating section 152 is integrally formed with insertion section 153.

The internal diameter size of the incorporating section 152 of lid side component 15 is more bigger than the outside dimension of the incorporating section 142 of matrix side component 14.Thus, the whole or major part of the incorporating section 142 of matrix side component 14 can be accommodated in the incorporating section 152 of lid side component 15.Incorporating section 142 under the state being accommodated in incorporating section 152, can while the inner peripheral surface of its outer peripheral face and incorporating section 152 slightly slidingly contacts moving axially along incorporating section 142,152.As shown in Figure 3 (c), bottom the opening peripheral part of the circular hole of incorporating section 152 and hole, position has required wall thickness, thus ensure that intensity.Further, as shown in Figure 3 (c), heavy section 151 engages and has periphery teat 151a in order to the end of the substrate 141 with matrix side component 14, and this periphery teat 151a stretches out to matrix side component 14 side than the openend of incorporating section 152.Although diagram, can not arrange hooking mechanism etc. on periphery teat 151a and substrate 141 yet, temporarily depart from for avoiding matrix side component 14 and lid side component 15.

As shown in Fig. 3 (b) He Fig. 3 (c), the linearly extension of part of matrix side component 14 side is leaned on from the ratio outer surface of heavy section 151 in insertion section 153, the position of linearly extension is observed from side and is identical width, that is, upper lateral margin line and lower lip line parallel.Thus, about insertion section 153, be formed with ladder difference at heavy section 151 and the border of this insertion section 153.As shown in Fig. 3 (a), the terminal edge of insertion section 153, centered by a P3, expand into the arc-shaped of the semicircle being of a size of the positive round of diameter with the width of insertion section 153.That is, 2 times of size of the size (size of the width of insertion section 153) of longitudinally along the longitudinal bands 2 by some P3 of this insertion section 153 terminal part width along the longitudinal bands 2 by some P that is insertion section 153.And, the outer shape of insertion section 153 is more bigger than the outer shape of insertion section 143, cross section incision becomes roughly inverted U-shaped, a part (being a part for insertion section 143 in Fig. 4) for the whole of insertion section 143 or side, insertion section 153 can be received, and the surface of the side, insertion section 143 of insertion section 153 can be made to abut with the surface of the side, insertion section 153 of insertion section 143.Namely, as shown in Figure 3 (c), the otch of insertion section 153 has: the inner surface 153a of the roughly the same shape of outer surface of the side, insertion section 153 at the position extended with lower portion fixed part 11 side of the insertion section 143 and circumference 153b extended to side, insertion section 143 from the periphery of this inner surface 153a.Further, although do not illustrate, also hooking mechanism etc. can being set at the circumference 153b of insertion section 153 and insertion section 143, temporarily departing from for avoiding matrix side component 14 and lid side component 15.

As shown in Figure 3, in the position that lower portion fixed part 11 side of insertion section 153 extends with the surface of matrix side component 14 opposition side, as the holding section for engaging with the chest portion 8 of bottom fixed part 11 in patchhole 20, there is cylindrical portion 154.As shown in Figure 3 (c), this cylindrical portion 154 is integrally formed with insertion section 153.As shown in Fig. 3 (a), the central point of the circle of cylindrical portion 154 still puts P3, and then, when lid side component 15 combines with matrix side component 14, observe from the thickness direction of longitudinal bands 2 and be configured to overlap with the center point P 2 of insertion section 143, but the configuration for other is described below.

Elastomer 16 is accommodated in the accommodation space S that formed by incorporating section 142 and incorporating section 152, for matrix side component 14 and lid side component 15 to away from direction force.Further, in this embodiment, elastomer 16 uses compression helical spring, and the substrate 141 of the bottom surface as incorporating section 142 of matrix side component 14 is fixed in its one end, and the other end is fixed on the heavy section 151 of the bottom surface as incorporating section 152 of lid side component 15.Certainly, although do not illustrate, compression helical spring also can be replaced to use rubber components as elastomer 16.And then rubber components is can in the shape of axial stretching, such as, also can be that the cylindric of same thickness or two ends are thick and along with the shape attenuated towards central authorities from an end face to other end.

Engaging part 13 is formed by the matrix side component 14, lid side component 15 and the elastomer 16 that illustrate before thus, make not having under any state (time usual) contacted with lid side component 15, as shown in Figure 4 (a), due to be accommodated in elastomer 16 pairs of matrix side components 14 in accommodation space S and lid side component 15 twocouese away from direction continue force, therefore become the state vacating gap between matrix side component 14 and lid side component 15.The size in the gap between this matrix side component 14 and lid side component 15 is to obtain the shift amount and required enough sizes that engage with round hole part 201 for making cylindrical portion 154 be shifted to round hole part 201 side.The size in the gap between this matrix side component 14 and lid side component 15 and the shift amount of thus obtained cylindrical portion 154 are such as 0.5mm is to being less than 1mm.

And, under the state (during gripping) of the center both sides of the particularly incorporating section 152 at the center of particularly incorporating section 142 and the heavy section 151 of lid side component 15 that hold with a hand the matrix side component 14 in engaging part 13, have the power of the active force of opposing elastomer 16 relative to elastomer 16 effect, elastomer 16 shrinks.Therefore, as shown in Figure 4 (b), not only the opening peripheral part of the circular hole of incorporating section 152 with substrate 141 to the direction relative shift abutted, and the inner surface 153a of insertion section 153 with the outer surface of insertion section 143 to the direction relative shift abutted, to make the gap between matrix side component 14 and lid side component 15 disappear, be therefore formed at the cylindrical portion 154 of insertion section 153 also to side, insertion section 143 relative shift.In addition, about engaging part 13, in order to turn back to the state shown in Fig. 4 (a) from the state shown in Fig. 4 (b), stop the state gripping engaging part 13.

As shown in Fig. 1 (b), bottom fixed part 11 is made up of slide block receptacle 17 and chest portion 18, and described slide block receptacle 17 and chest portion 18 are formed at the end of the longitudinally of longitudinal bands 3.This slide block receptacle 17 is well-designed for making the shape of slide block 7 movement swimmingly.In addition, bottom fixed part 11 has retainer 19 in slide block receptacle 17 side of chest portion 18, when wherein retainer 19 is for moving to foot fixed part 11 side at slide block 7, keeps the main body 7a of slide block 7.Further, as shown in Fig. 5 (a), near the bottom fixed part 11 of longitudinal bands 3, the first element 4b engaged with the first element 4a of bottom fixed part 10 is configured with.

As shown in Fig. 5 (a) to Fig. 5 (c), chest portion 18 has the patchhole 20 at bottom fixed part 10 side opening.Patchhole 20 extends to the side contrary with bottom fixed part 10, and its degree of depth is illustrated in figure 6 the size part of the linearly extension of the assembly of the insertion section 143,153 of engaging part 13 roughly can inserted.Further, as shown in Fig. 5 (a), most deep medial surface 20e point centered by a P4 of patchhole 20, caves in into the arc-shaped being of a size of the semicircle of the positive round of diameter with the longitudinally along longitudinal bands 3 of patchhole 20.That is, the longitudinally along the longitudinal bands 3 by some P4 of the most deep medial surface 20e of this patchhole 20 is of a size of 2 times of the size of the width along the longitudinal bands 3 by some P4 of patchhole 20.Further, the most depression of semicircle shape of deep medial surface 20e of patchhole 20 and the position of the semicircle shape of the terminal part of insertion section 153, the concentric circles that the depression for the semicircle shape of the most deep medial surface 20e of patchhole 20 is bigger.But when the most deep medial surface 20e of the position of the semicircle shape of insertion section 153 terminal part and patchhole 20 abuts, some P3(also comprises a P2) with put P4 and overlap.

In addition, patchhole 20 is formed with round hole part 201 for engaging with the cylindrical portion 154 of engaging part 13 at inner side surface 20a.As shown in Fig. 5 (a), about this round hole part 201, some P4 is still the central point of the circle of this round hole part 201.Therewith concomitantly, by making the position of the semicircle shape of the terminal part of insertion section 153 abut with the most deep medial surface 20e of patchhole 20, the P3 at the center of the circle of the cylindrical portion 154 as engaging part 13 is overlapped with the P4 at the center of the circle as round hole part 201.Thickness around the patchhole 20 of chest portion 18 is relatively thick, thus ensure that the intensity of chest portion 18.

As shown in Fig. 5 (a), the inner side lower surface 20b being positioned at the end side of the longitudinally of longitudinal bands 3 of patchhole 20 holds and tilts towards the first element 4b side direction oblique upper with predetermined tilt angle alpha (such as the angle of inclination of about 7 degree) relative to the width of longitudinal bands 3 a succession ofly from openend to inboard.Further, when pull-up slide block 7, tilt angle alpha is identical with the anglec of rotation that bottom fixed part 11 rotates relatively with bottom fixed part 10.In addition, in this embodiment, relative with inner side lower surface 20b inside upper surface 20c along the width of longitudinal bands 3 a succession of linearlyly extend to most deep medial surface 20e.Certainly, when the terminal edge of insertion section 143,153 be not arc-shaped but straight line, although not diagram, but also can be, from the position of the P4 at the center of the circle as round hole part 201, roll oblique inclined plane as with tilt angle alpha to the first element 4b, the assembly of insertion section 143,153 can be inserted swimmingly and some rotation centered by a P4.

In addition, as shown in Figure 6 (a), the configuration of round hole part 201 of the cylindrical portion 154 of engaging part 13 and the patchhole 20 that is formed at chest portion 18 is set to, when cylindrical portion 154 overlaps with round hole part 201, it is also the center P3 of the circle of cylindrical portion 154 that first element 4a and the first element 4b is positioned at by the center point P 4(of round hole part 201) centered by circular orbit on, and then when the first element 4a rotates for pivot with center point P 4, this first element 4a engages with the first element 4b.

Further, chest portion 18 has the locking teat 181 extended from the opening periphery of the inner side surface 20d side relative with the inner side surface 20a of patchhole 20.The medial surface of this locking teat 181 and the inner side surface 20d of patchhole 20 are the same face.Assembly in the insertion section 143,153 of engaging part 13 relative to the patchhole 20 of chest portion 18 be inserted into abut with most deep medial surface 20e time, locking teat 181 can engage with the locking depressed part 145 of engaging part 13.And then, although the shape of engaging part 13 side of locking teat 181 not diagram, be the arc-shaped centered by a P4, not contact with engaging part 13 when engaging part 13 rotates.In addition, about chest portion 18, the end side of the longitudinally of the longitudinal bands 3 in the openend of patchhole 20 is provided with guiding jut 182.This guide protrusion portion 182 comprises the inclined plane be connected with the inner side lower surface 20b of the patchhole 20 of following chest portion 18.

By making locking teat 181 engage with the locking depressed part 145 of matrix side component 14 when cylindrical portion 154 overlaps with round hole part 201, thus ensure that the state abutted with the side of side, insertion section 143 of rib 144 and the inner side surface 20d of patchhole 20 with the surface of lid side component 15 opposition side in matrix side component 14.Therefore, when engaging part 13 makes the size restoration of thickness direction, cylindrical portion 154 can be made reliably to be shifted towards the direction engaged with round hole part 201.Namely, gap is there is between surface that is such as in matrix side component 14 and lid side component 15 opposition side and the inner side surface 20d of patchhole 20, when engaging part 13 makes the size restoration of thickness direction, cylindrical portion 154 can not be made suitably to be shifted towards the direction engaged with round hole part 201, can to prevent that cylindrical portion 154 is bad with the engaging of round hole part 201.In addition, although do not illustrate, also locking teat 181 can be arranged at engaging part 13 contrary to the abovely, and the locking depressed part 145 engaged with the locking teat 181 of engaging part 13 is arranged at chest portion 18.

About having the bottom fixed part 11 of chest portion 18 of such formation and above-mentioned bottom fixed part 10, comprise the first element 4a about the element 4(in longitudinal bands 2) and the element 4(of longitudinal bands 3 comprise the first element 4b.) engage while the example of action that can link under the state of pull-up slide block 7, use Fig. 6 to be described.

With the position beyond the assembly of the insertion section 143,153 of right hand gripping engaging part 13, make the full-size of the thickness direction of engaging part 13 less than the internal diameter size of the longitudinally along longitudinal bands 2 of the patchhole 20 of chest portion 18, the position of cylindrical portion 154 is shifted to matrix side component 14 side.Next, the continuation right hand grips the position beyond the assembly of the insertion section 143,153 of engaging part 13 and holds chest portion 18 with left hand, while the state that the position maintaining cylindrical portion 154 is shifted to matrix side component 14 side, while make the assembly of the insertion section 143,153 of engaging part 13 be inserted into the inboard (such as, while making the assembly of this insertion section 143,153 abut with the inner side lower surface 20b of patchhole 20) of the patchhole 20 of chest portion 18.Now, the assembly of the patchhole 143,153 of engaging part 13 moves after placing being placed in the medial surface of the guiding jut 182 given prominence to from the openend of patchhole 20 temporarily, thus is directly directed to the inner side lower surface 20b of patchhole 20.Therefore, it is possible to simply to the action transfer assembly of insertion section 143,153 is inserted in patchhole 20.

And then, maintain the state that the assembly of insertion section 143,153 abuts with the inner side lower surface 20b of patchhole 20, the engaging part 13 of the state keeping the size of thickness direction to diminish is inserted, until the most deep medial surface 20e of the end of the assembly of insertion section 143,153 and patchhole 20 abuts.Thus, as shown in Fig. 6 (a) He Fig. 6 (b), when the assembly of insertion section 143,153 abuts with the most deep medial surface 20e of patchhole 20, the cylindrical portion 154 of engaging part 13 is in the position overlapped with the round hole part 201 of patchhole 20.

Then, stop the action (right hand leaves from engaging part 13) gripping engaging part 13, make the size restoration of the thickness direction of engaging part 13, the position of cylindrical portion 154 is shifted to matrix side component 14 opposition side (originally side).Now, the shift amount of cylindrical portion 154 position and the gap between matrix side component 14 and lid side component 15 measure-alike, but this is because the locking depressed part 145 of engaging part 13 and the locking teat 181 of chest portion 18 engage, therefore the bearing surface of matrix side component 14 and the side, insertion section 143 of rib 144 and the inner side surface 20d of patchhole 20 becomes the application point of the active force obtained from elastomer 16.

When cylindrical portion 154 overlaps (comprising the situation that cylindrical portion 154 and round hole part 201 link and the situation both sides do not linked here) with round hole part 201, first element 4a and the first element 4b is positioned at such position: using the some P4(at the center of the circle as round hole part 201 be also the P3 at center of circle as cylindrical portion 154) centered by circular orbit on, and when the first element 4a rotates for pivot with center point P 3, this first element 4a engages with the first element 4b.

And, cylindrical portion 154 overlap with round hole part 201 (here just cylindrical portion 154 and round hole part 201 situation about not linking) state under, when maintenance with the right hand grip engaging part 13 state and with left hand pull-up slide block 7, inner side lower surface 20b due to the patchhole 20 of chest portion 18 is the stopper section of engaging part 13, therefore prevent interlock, longitudinal bands 3 rotates counter-clockwise to longitudinal bands 2 side.Therewith concomitantly, until the assembly of the insertion section 143,153 of engaging part 13 abuts with the inside upper surface 20c of patchhole 20, under the most deep medial surface 20e of the semicircle shape part of the terminal part in insertion section 153 and patchhole 20 keeps the state comprehensively abutted, chest portion 18 with a P4 for pivot rotation and be in the state shown in Fig. 6 (c) He Fig. 6 (d).The anglec of rotation of chest portion 18 is identical angles with the tilt angle alpha of the inner side lower surface 20b of patchhole 20, such as about 7 degree.Further, by pull-up slide block 7, the element 4(of longitudinal bands 2 is made to comprise the first element 4a) comprise the first element 4b with the element 4(of longitudinal bands 3) engage.

On the other hand, under the state that cylindrical portion 154 and round hole part 201 link, the right hand is left from engaging part 13, part (hand held can be the right hand also can be left hand) such as beyond other the slide block 7 holding chest portion 18 simultaneously pull-up slide block 7, because cylindrical portion 154 and round hole part 201 link, therefore prevent interlock, longitudinal bands 2 is rotated clockwise to longitudinal bands 3 side.Therewith concomitantly, under the most deep medial surface 20e of the semicircle shape part of the terminal part in insertion section 153 and patchhole 20 keeps the state comprehensively abutted, the assembly of the insertion section 143,153 of engaging part 13 for pivot rotates until abut with the inside upper surface 20c of patchhole 20, and becomes the state shown in Fig. 6 (c) He Fig. 6 (d) with a P4.The anglec of rotation of engaging part 13 is also identical angles with the tilt angle alpha of the inner side lower surface 20b of patchhole 20, such as about 7 degree.Further, by pull-up slide block 7, make described same with previous, make the element 4(of longitudinal bands 2 comprise the first element 4a) comprise the first element 4b with the element 4(of longitudinal bands 3) engage.

In addition, because the tilt angle alpha of the inner side lower surface 20b of patchhole 20 is identical with the angle that the assembly of the insertion section 143,153 of engaging part 13 rotates, therefore as shown in Figure 6 (c), the assembly of the insertion section 143,153 of engaging part 13 is in the state extended as the crow flies along the direction (width of longitudinal bands 3) orthogonal with the longitudinally of longitudinal bands 3, thus outward appearance is good.

In addition, in the insertion section 143 by engaging part 13, the assembly of 153 takes off from the patchhole 20 of chest portion 18, again grip the insertion section 143 in engaging part 13, position (being formed with the assembled part of the position of the incorporating section 152 of the heavy section 151 of lid side component 15 and the incorporating section 142 of matrix side component 14) beyond the assembly of 153, elastomer 16 is shunk, the size of the thickness direction of engaging part 13 is diminished, thus, cylindrical portion 154 is made to remove the link of cylindrical portion 154 and round hole part 201 to the displacement of matrix side component 14 side, and then by the insertion section 143 in engaging part 13, the assembly of 153 is extracted from the patchhole 20 of chest portion 18.

As mentioned above, by the formation of the engaging part 13 of bottom fixed part 10 shown in this embodiment 1 and the chest portion 18 of bottom fixed part 11, can reliably and easily carry out for linking the operation of bottom fixed part 10,11 and the operation for pull-up slide block 7.
